USE OF ADMINISTRATIVE RECORDS TO DESCRIBE LONGITUDINAL PATTERNS OF HEALTH-SERVICES USE AMONG VETERANS

Administrative records of the Department of Veterans Affairs (DVA) and the National Death Index were linked to create a four-year longitudinal database that describes the clinical status, hospital and nursing home use, and mortality for a nationwide cohort of persons admitted to DVA nursing homes (n = 23,039). Using Social Security Numbers as identifiers, the records of only 6% of these persons had logically inconsistent or implausible patterns. Nineteen percent of the remaining records had correctable logical errors. Information on the creation, consistency, and potential uses of this database may prove useful to health services researchers interested in describing longitudinal patterns of health care use across multiple settings within and outside the DVA.
